Technically, I’m sure it’s possible with the 2016 model… If you crack open the left side chassis, there is an unpopulated Micro USB, all ready to go… but it’s also missing a bunch of unlabelled passives, and there’s no support in the SDK for the left AUX, so you’d likely have to write your own firmware + SDK to get the data out.

Then, dear Muse People,
will MU02 will broadcast the signal connected to 2nd AUX channel? or As Enigma644 mentioned, I have to modify the firmware?
Also, how the MU01 communicates with two AUX? same microusb connection?
